SYLLABIC TYPE-WRITER.

Specification of Letters Patent.

Patented Dec. 10, 1918.

Application filed January 4, 1917. Serial No. 140,583.

To all whom it may concern:

Be it known that I, Lrouneo TroLr, physician, a subject of the King of Italy, residing in the city of Rome,'in the Kingdom of Italy, have invented certain new and useful Improvements in Syllabic Type-\Vriters, of which the following is a complete and. full description.

The present invention refers to those typewriters which are generally known as syllabic typewriters and which permit of contemporaneously printing several letters. ()ne of the objects of the invention is to provide a typewriter of said class which will permit of printing at a stroke two, three, or even more letters or signs, arranged in any way whatever, without preventing the use of the single keys in the same manner as in the ordinary typewriters, viz: for printing a letter, or sign, at each stroke, this new typewriter being arranged in such a manner that the shifting of the carriage is automatically controlled in accordance with the number of spaces necessary for printing the group of signs lowered together.

The contrivances of the present invention as hereinafter particularly described, are illustrated in the annexed drawings in which;

Figure 1 shows. a top view board;

Fig. 2 a longitudinal section of the same;

Figs. 2 to 7 show on an enlarged scale the details of the eontrivances of the typewriter and more especially;

of the key- Fig. 3 shows an elevation of the shifting wheel for the carriage;

Fi 4 showsan elevation of a tooth controllihg the shifting gear together with the driving gudgeon of the same;

Fig. 5 shows a top view of the said tooth taken alone; i

Fig. 6 shows a lateral elevation of the regulating block of the said tooth;

Fig. 7 shows a horizontal section, on the line A B of the Fig. 3, the bridgestanding above the aforesaid wheel being omitted.

The figures are intended to be more or less diagrammatic illustrations of the various parts, the size of which, especially of those of the keyboard can be altered at will, provided that such alterations be consistent with the performance of the fingers of the typist. W

The above mentioned improvements com prise: a special keyboard with keys arranged in groups; a new shifting gear for the tarriage moving thesame for a variable mumber of spaces from the rightto the left, and a special arrangement and construction of key levers for each group of. the keyboard.

This typewriter embodying the contrivances, which form the object of the present invention, can be built of the same shape and size as the usual typewriters, by conveniently arranging the keys and the levers in such a way that they will be more compactly disposed than in the usual typewriters. It will be convenient to give this new machine the same width as the usual typewriters so as to enable the typist to act -contemporaneously with one hand at least on two groups of keys, aswill be explained hereinafter.

The keyboard comprises a number of groups of keys. I11 Fig. 1 are shown three equal groups, but, evidently, the number of the groups, as well as the number of the keys contained in each group, can be altered according to the circumstances.

The groups of keys instead of being developed in width are developed in depth Each group, in the example shown (Fig. 1), consists of alternated rows of three and four keys, and the number of the rows is determined by the number of the signs to be printed. In Fig. 1, are shown groups with seven rows, but this arrangement although convenient, need not be necessarily adhered to in all cases.

hen the keys -4- (Fig. 2) are lowered they enter the recesses -5-provided for them in the inclined plate -6 below them.

This is a convenient arrangement, as the fingers of the typist during the writing need not pass between the keys. The first group of keys comprises, besides the letters, also the ciphers and other conventional signs.

In this way by means of an ordinary shift key, as already used in some typewriters, for-raising the carriage to the first height, the capital letters ean be obtained and by raising the same t the second height, the signs, while the position of the carriage remains normal for the small letters. v

The printing bars of the first group instead of bearing only two rows of letters, vbear also a third row containing the signs.

- This arrangement of the double elevation of the carriage as used in some old system.

of typewriters, has been abandoned in nearly all the new systemsfand has been substituted by an addition of keys in order'to savetime. With this new typewriter howtime 'becomesabsolutely insignificant in viewofthefspecial means adopted in it for speeding thework. I

The arrangement of the letters on the keys as shown in-Fig"; -1 need not be strictly adjhered to, but it is {advisable to maintain the vow,els as shown in the drawing, as experience has proved that the position thereof is i one ofthe most conv'enient'and advantageous a for the difierent combinations of letters which may be met with in writing.

Tith this typewriter'theq'three groups of i1 keys which are similar, can be operated in v dependentlyand each one is sufficient to I formed a-- eomplete keyboard or an' ordinary ,ever, the old arrangement can be con-,- 'veniently. maintained because the loss of write correctly just as if each of them typewriter, with the only difference that when writing by means of the second or the third group separately, the interval ofthef letters will-be of; twoor three spaces instead of'one, which might in some cases beagde- 1 sirable feature, as for instance when a'er tain word or sentence is to be written with- (hit the use of brackets 01' other signs.

It isto be noted-that. all 'the printingbars 7'' of the first group (Fig, 1) strike 1.

in the point marked with the'reterence- Ill 1 meral -7-.- in the'drawingrthose9-85- of the second group in the point and The distance between the po1iits -7-,

same as the interval between the letters in an ordinary typewriter. In this way by 'de' pressing'a key of the first group, another of the second group vand one of the third group, at the same time, three letters in a line, at 1 bility of striking onekey at a time, the same as with the ordinary typewriter. h

.To this end a special systei'nof escapement which will be fully described hereinafter, has been provided for. p

It will also be noted'that three groups of keys areprovided with corresponding .space such a way with the respective groups, that 'they are operated whenever a key is lowered.

When the space key -10-'-- of the first group is lowered the carriage advances-one space,

with the space" key -'1'l of the second mits of writing them in thefo f third group the carriage advances two spaces, and with the space key -12- of the third group the carriage advances three spaces. As .will be seen this arrangement presents enormous practical-"advantages.

As has been explained before the space;- keys are moved by depressing the, printing keys, 'buti'they' can be also operated hidepende'ntly of said jkeysas in the ordinary, typewriters.

of this new typewriter.

For instance, wishing to write the words .your idea' this new kind of typewriter perner: you r-i dea whereby the letters From a e pr n y means o t three;

group andthe grouptothe right are for the: y I;

contemporaneous action of the fingers of the right hand while the fingers of the left hand act on the keys of the first group and on the key cbntrollingthe" carriage height.

Hereafter is described the escapementby means which all the above operations are actually performed.

This new system of escapement consists of a single wheel, by means ofwhich it'is possible, by lowering a key of "one orthe other I I of the groups, to cause the' advancement of the carriage by one or more spaces. As shown in the drawing the number of these spaces is limited to threeyand it has been found by experience that this number of spaces is the most convenient and therefore to be preferred, but nothing prevents the adoption of only two spaces, or an increase to four spaces, without substantially alteringthe'action of the escapement.

The mechanism consists essentially of a toothed wheel .,13 (Figs. 3 to 7 which is rigidly connected withthe shaft 1 ll-by means of a clip -15 and runs in guides Fig. 7 this wheel is toothed inside, andsome of the teeth are indicated therein'with I, II III, and IV, the tooth I is at the initial os'ition of rest of the regulating" tooth o the escapement. which will be described hereafter, while the other three teeth are at the 16- and -'17 (Fig. 3); As shown in positions which the same tooth can take in accordance with the three performances of the typewriter. I

The shift -1 lconnected rigidly with the wheel carries at its end a pinion 18, which gears with the rack bar'l9-.

- Said pinion is connected with the shaft 'l iby a mud 2()- which turns the shaft when the rack bar moves fromthe right to the left, in which case also the wheel ;-13 is compelled to turn in the same di rection as the pinion.

When the carriageis pushed back to its initial position in order 'to begin to write a line, the pawl moves automatically out of gear and the pinion 18- turns without imparting.movement to the shaft -14 '-25. having a U shaped recess within which the tooth 22. works. Thetooth -22- and a fixed tooth '-29 are carried by an elevating member 31 connected with the shaft -28--. Thebox '-25 with a support form another system which will be described hereafter. When the typewriter is at rest, the toothed wheel -13 is locked and consequently also the pinion 18 and the rack bar 19.

- In operation, if for instance, one of the keys belonging to the group -I (Fig. 3)

be lowered thus-raising with its lever the portion -38 of the universal bar 26 provided with three steps 38-, 39--, 4:0 the elevation member 31 will be raisedto a certain height by means of the bar 28- connected with the bar 26-.

The said member -31 thus moves in the box 25 to such a height as is necessary to raise the movable tooth -22 out of the space in which it was kept locked between the two teeth I and II of the wheel 13,

its place being then taken by the fixed to'oth,

29+ placed therebelow. It then happens that the wheel l3- remains still locked by the fixed tooth -29 while the free movable tooth -22 will followthe impulse received from the spring 32- (Fig. 4) and tends to move in the direction indicated by the arrow --33- and will move till it is stopped by the first of the three steps -1- 2' -3 of the U shaped'box that is'the step 1"- (Fig. 6). By releasing the key the tooth 2-2 will go down as much as it had been raised, pulling with it the upper part of the box -25.. The tooth -22 Wlll be ready to engage in the next space between two teeth of the toothed wheel, that is in the space II-, while the fixed tooth 29 moves free of the wheel 13 which will now, yielding to the pull of the spring of the rack bar, be able to turn in the direction indicated by the arrow '21-, until the movable tooth 22. is again stopped by the stop ).-'l of the box.

The whole system will now return to its original position of rest but the rack bar will be displaced from the right to the left to such an extent asto allow the carriage to advance a distance equal to the spaces occupied by the printed letters.

It is necessary now to explain particularly how it happens that the movable tooth in going down drags behind the upper part of the box 25-. As shown in Fig. 6 the box -25 which surrounds the teeth '22 and 29 can move vertically on the lower part 30- .of the same, against the tension of two springs 3-fl coiled around the posts -'35, pushing these posts into the opposite holes -36- drilled in -30. \Vhen the movable tooth 22- releases the box 25 the latter returns in its former position by means of the aforesaid springs.

Supposing now that one of the keys of the group -2 is lowered, its lever, which has the same course as that of the first group of keys, meeting on its w-ay the universal bar '-26 in its part -39 will raise same for a double length thus bringing the whole running system in the U-shapd box -29- to a double height, so that the movable tooth .22- will be stopped by the step 2 of the box and the tooth is thus ready to engage the space III.of the wheel 13. The

same happens with the third group of keys,

for which the movable tooth -22' (the running system in the box 25 being raised to the third height) will engage in the space IV' of the wheel -'13-. Thus in the same way described-before, a displacement of the carriage by two or three spaces can be obtained.

In a few words this new invention con sists in a mechanical arrangement as de scribed, which permits of writing several alphabetic letters at the same time in a-line on the paper with the usual intervals between the letters and the words of the same horizontal line, as in the case with the ordinary typewriters, but with a remarkable economy of time, the said arrangements be-- ing in whole or in part, and in several'ways,

applicable to the typewriters now in use and leaving to the typist the choice of using either the new system, the operation of which has beendescribed, or the old system of writing one letter at a time.
